ABSTRACT:
A display apparatus is disclosed which uses an improved precharge method and includes a reduced number of precharge switches. A pixel array section includes gate lines disposed in the direction of a row, signal lines disposed in the direction of a column, and pixels arranged in rows and columns at points at which the gate lines and the signal lines intersect with each other. A precharge switch is connected between a precharge line and each of the signal lines. A precharge drive circuit performs batch precharge wherein it drives the precharge switches at a time within a horizontal blanking period preceding to a horizontal scanning period to apply a precharge signal of a first level at a time to the signal lines and sequential precharge wherein it successively drives the precharge switches within the horizontal scanning period to successively apply a precharge signal of a second level to the signal lines.
